A view from the west caldera rim of Cerro Azul shows a caldera bench covered with young lava flows in the foreground and part of the blue caldera floor lake and a tuff cone filled with greenish lake water. The photo was taken in July 1998, shortly before an eruption in September 1998 from vents on the south caldera bench and the west caldera floor.
